Add a warning when gpuClock is called from the host (#27022)
Inspired by this discourse
topic.
This PR adds a warning when gpuClock is called from the host. When
that happens we always return 0 silently. Understandably, that can be
confusing.
There's a question of whether that warning should be suppressable when
the same loop is executed both on the CPU and the GPU, for example.
However, I see gpuClock as an advanced feature that should not be
widely used. So, this PR doesn't go that far.
